How to check the vertex/edge/polygon count of one or more object?
Script to print stats to system console

Script prints the stats of selected mesh object to system console.

import bpy
from bpy import context

sumfaces = []
for o in context.selected_objects:
    if o.type != 'MESH':
        continue
    me = o.data
    verts = len(me.vertices)
    edges = len(me.edges)
    faces = len(me.polygons)
    sumfaces.append(faces)
    print("%s: verts:%d edges:%d polys %d"
            % (o.name, verts, edges, faces))

print("total polys %d" % sum(sumfaces)) 


Sample output.

Cube: verts:8 edges:12 polys 6
Suzanne: verts:507 edges:1005 polys 500

total polys 506
